In a rectifier assembly, silicon diodes 13, 14, 15, 16 (Fig. 1), are mounted on copper or aluminium cooling plates 2, 3, 4, 5, respectively, the square shanks of the diodes being secured in apertures 20 (Fig. 5), in the plates by nuts 19 on threaded bolts 17 which effect electrical connections between cathodes and plates, and each diode protrudes through a circular aperture 21 in the adjacent plate 1, 2, 3 or 4, an anode lead 18 from each diode being connected to one of terminals 9-12 which are insulatedly clamped to the assembly on one or other alternately of two tiebolts 6 which also insulatedly secure the plates in position, the ends of the terminals projecting above the plates and being insulatedly clamped in alignment by a third tiebolt 24. The diodes may be connected in series by means of metal sleeves 33 clamped between appropriate plates and terminals ; a parallel connection arrangement is achieved by interconnecting terminal extensions 22 which are located at opposite sides of adjacent plates, and by interconnecting terminals 9-12, alternate terminals being, if desired, of the modified shape shown in Fig. 7, to enable interconnection to be effected with one bus-bar. Other methods of connecting the diodes inter se, and the location of apertures 20 and 21 in the plates, are described.

Title: Improvements relating to overload clutches
IPC: F16D43/21
Filed: 1963-07-03
Abstract: 975,553. Friction clutches. J. WALTERSCHEID, and B.WALTERSCHEID-MULLER. July 3, 1963 [July 3, 1962], No. 26441/63. Heading F2C. A torque-limiting friction clutch for coupling driving and driven members 4, 7 includes wedging balls 16, 19 acting in conjunction with diaphragm springs 5, 6 having drooping load characteristics, Fig. 3, each spring being prestressed during assembly to a point A lying in the flat-topped region of the curve near its junction with the negative-gradient region, to operate over the portion AB. At the desired load torque the balls 16, 19 operate to deflect the springs 5, 6, the reduced forces exerted by which ensure slipping of the clutch. Preferably the arrangement is such that the balls do not begin to operate until the torque transmitted exceeds 70- 90% of the desired maximum torque. As wear occurs the initial load point moves between points A and C so that the torque limit remains substantially constant. The pressure plates 12, 13 have projections 22 extending into recesses 20 in the springs 5, 6 to allow angular lost motion, of unequal extent, between the respective pairs of members. In a second embodiment, Fig. 4 (not shown), a single spring and set of wedging balls only are employed.

Filed: 1920-09-15
Abstract: 173,037. Seiler, W., and Hammond, C. Sept. 15, 1920. Locking.-The passage of fuel to a motor vehicle engine may be prevented, to prevent unauthorized use thereof, by locking a valve situated between the carburettor and the engine. In one construction, shown in Fig. 2, the valve casing 4 is integral with the engine casing 1, and in another ccnstruction, shown in Fig. 1, it is secured thereto by lugs 6 and bolts 7 entered from within the casing. A ball valve 8 is pressed by a spring 11 on to a valve seat 10 screwed into the open end of a socket 9. The portion of the ball valve projecting through the valve seat contacts with a diaphragm 15 which is pressed inwards when locking mechanism on the other side is operated. As shown, the mechanism comprises a number of tumblers 13, the innermost one having a stem 14 forced against the diaphragm by setting the tumblers at a particular combination, thereby opening the valve and permitting fuel to pass through via a passage 17 and an aperture 18. The lock is operated by a spindle 21.

Abstract: 1510203 Ion sources SHARP KK 23 June 1975 [21 June 1974 22 Oct 1974(2)] 26599/75 Heading H1D An ion source comprises a cathode 42 through which a discharge gas is introduced and an anode 43 of spiral construction, an electric field being established in use between the anode and cathode and a magnetic field being produced by current flow through the anode, the two fields being orthogonal thereby dispensing with the usual surrounding magnetic coil. An alternative cathode shape is a planar spiral interleaved with a planar spiral anode with a cathode current direction to provide a further magnetic field in the same direction as that caused by the anode current, Figs. 1 and 2 (not shown). In Fig. 3 (not shown) a similar arrangement of interleaved anode and cathode spirals are in the form of a constricted cylinder. In Fig. 4 (not shown) anode and cathode segments are arranged alternately and external connecting wires provide a spiral configuration. In Fig. 5 (not shown) a stack of planar spiral anode-cathode structures is used. In Fig. 6 (not shown) a plurality of anode-cathode structures is arranged over an imaginary curved surface to provide high beam intensity. An extraction and focussing electrode comprising a helically wound wire to which a potential is applied and through which a current passes having a cylindrical portion and a conical portion adjacent the exit aperture of the ion source is described with reference to Fig. 8 (not shown). Additional excitation may be provided by microwave or laser radiation enabling cyclotron resonance of electrons emitted from the cathode to be achieved.

Abstract: 1,093,987. Priority circuit arrangements for digital computer. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 15, 1966 [June 18, 1965], No.26706/66. Heading G4A. A circuit for giving priority to one of a plurality of incoming request signals which are divided into groups e.g. A, B, C, D, arranged in accordance with a given priority rating; the request lines of a group also being arranged in accordance with a given priority rating and each request line being connected to a normally closed gate having two outputs a, b comprises a first logical circuit P, connected via corresponding OR gates 10-40 to all the first outputs of the gates of corresponding, groups A-D, the output of the circuit P1 being connected to a first memory G1, and a, second logical circuit P 2 . connected via OR gates 01-04, one to the second outputs of the first line of each group, one to the second outputs of the second line of each group &c., the output of circuit P 2  being connected to a second memory, and at least a two-phase clock pulse cycle arranged so that during a first phase clock pulse the normally closed gates are opened to pass request signals to the first logical circuit which determines which group has the highest priority stores a signal identifying the said group and supplies the said signal to to the signal transformer which converts the signal to a pulse 1 out of n lines to enable on a second phase pulse cycle the gates of the appropriate highest priority group which pass signals to the second logical circuit which identifies which line has the highest priority. A logical circuit for determining priority e.g. P1 is shown in Fig. 4. Assuming seven inputs, with number 7 having the most significance and numbelr 1 the least, then the circuit must identify the input line having the highest significance. It does this by setting a counter E, F, G to read the number of the highest significant line, the input to E receiving the signal 4 + 5 + 6 + 7, the input to F receiving (6 + 7).E + (2 + 3).E and G receiving (7.E.F) + (5.E.#F) + (3.#E.F) + (1.#E.#F), the inputs being applied via AND gates s1, s2,. s3 enabled by clock pulses t2, t3, t4. The arrangement is such that if a line of one group is enabled and a request from a group of higher priority is indicated then the input of the first line is inhibited and the input on the second line is enabled (Fig. 1, not shown).
